Abstract

BACKGROUND: Microalbuminuria predicts cardiovascular events in diabetic and non-diabetic patients. But, few studies have addressed the relationship between microalbuminuria and cerebral infarction. We determined the incidence of microalbuminuria in non-diabetic subjects with cerebral infarction and investigated the relationship between urinary albumin excretion and risk factors of the stroke.
METHODS
Urinary albumin excretion rate, 24 hours blood pressure monitoring, fasting serum lipid profiles, fibrinogen, fasting glucose, insulin and c-peptide were evaluated in 50 non-diabetic patients with acute cerebral infarction and matched 48 controls.
RESULTS
Microalbuminuria was detected in 23 of 50(46%) patients with acute cerebral infarction and 4 of 48(8%) control subjects. Hypertension was present in 13 of 23(57%) microalbuminuric patients and 9 of 27(33%) non-microalbuminuric patients. In the microalbuminuric patients with cerebral infarction, diastolic blood pressure and fasting glucose were significantly greater than the control group. But, no difference in systolic blood pressure, lipid level, fibrinogen, fasting insulin and c-peptide level.
CONCLUSIONS
The prevalence of microalbuminuria in patients with cerebral infarction was higher than controls and it was associated with increased diastolic blood pressure(DBP) and fasting blood glucose(FBS). Therefore, microalbuminuria is associated with thrombogenic cerebral infarction and it was partly mediated by DBP and FBS.
